The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Vegetarian diets, particularly vegan diets, are associated with lower bone mineral density

This post includes a synopsis of a study published in the American Journal of Clinical Nutrition October 2009 vol. 90 no. 4 943-950 and a recipe for kale meatballs.

The aim of the study was to estimate the effect of vegetarian diets on bone mineral density (BMD) by using a meta-analytic approach. Nine studies of 2749 subjects (1880 women and 869 men) were included in the analysis.

The study found:
(a) Overall, bone mineral density was 4% lower in vegetarians than in omnivores at both the femoral neck and the lumbar spine.
(b) Compared with omnivores, vegans had a significantly lower lumbar spine bone mineral density (6% lower).

To conclude: The study suggests that vegetarian diets, particularly vegan diets, are associated with lower bone mineral density.
